Hello Michele,

I also wanted to add, in case there is any confusion, that this may shed
some light:

https://gcc.gnu.org/onlinedocs/gccint/Configure-Terms.html

Another option, which may be better, is to build gmp, mpfr and mpc in-tree
with the GCC source when you build it.  Extract mpfr, gmp and mpc into the
source code so it is laid out:

gcc-5.3.0/gmp
gcc-5.3.0/mpfr
gcc-5.3.0/mpc
gcc-5.3.0/isl (if also inclulding isl)

then configure:  mkdir gcc-build && cd ../gcc-build && (needed flags here)
../gcc-5.3.0/configure (configure options here excluding --with-gmp
--with-mpfr --with-mpc)

Sincerely,

William
